ABS Service



Failure to observe the following precautions may result in system damage.

Performing diagnostic work on the ABS-VI requires the use of a Tech 1® Scan diagnostic tool or equivalent. If unavailable, please refer diagnostic work to a qualified technician.
Before performing electric arc welding on the vehicle, disconnect the Electronic Brake Control Module (EBCM) and the hydraulic modulator connectors.
When performing painting work on the vehicle, do not expose the Electronic Brake Control Module (EBCM) to temperatures in excess of 185°F (85°C) for longer than 2 hours. The system may be exposed to temperatures up to 200°F (95°C) for less than 15 minutes.
Never disconnect or connect the Electronic Brake Control Module (EBCM) or hydraulic modulator connectors with the ignition switch ON or damage to the system will occur.
Never disassemble any component of the Anti-Lock Brake System (ABS) which is designated non-serviceable; the component must be replaced as an assembly.
When filling the master cylinder, always use Delco Supreme 11 brake fluid or equivalent, which meets DOT-3 specifications; petroleum-base fluid will destroy the rubber parts.
